The base 200 and the driving unit 300 are coupled by inserting the driving unit guide protrusion 330 into the driving unit guide groove 230.

That is, the magnet 340 is located on the side where the yoke 240 and the coil 260 are formed, and the driving part guide protrusion 330 has the rolling member 250 located on the lower side.

In this case, the driving part guide protrusion 330 may further include a rolling member guide 350 at a position corresponding to the rolling member 250 on the bottom surface.

The rolling member guide 350 has an arc shape so as to correspond to the rotational motion range of the driving unit 300, and a portion of the upper side of the rolling member 250 may be inserted into a groove having a'^' shape in cross section.

Accordingly, when the driving unit 300 rotates, friction with the base 200 is minimized so that the driving unit 300 may be driven with a relatively small force.

In addition, when the driving unit 300 is coupled to the base 200, it is easily fixed without a separate fixing structure or member due to the force generated between the magnet 340 and the yoke 240.

Meanwhile, the first plate 410 is coupled to the first rotation shaft 211 and the first drive shaft 311.

In this case, the first plate 410 may be coupled to the upper surface of the driving unit 300 by spaced apart from the upper surface of the driving unit 300 by the first rotation shaft step portion 211a and the first drive shaft step portion 311a.

In addition, it is preferable that the top surface of the first rotation shaft step portion 211a and the top surface of the first drive shaft step portion 311a are formed to have the same height.

Accordingly, when the first plate 410 continuously rotates within a certain angle, it is possible to minimize the occurrence of triboelectricity with the upper surface of the driving unit 300.

In addition, it is possible to prevent abrasion occurring on the lower surface of the first plate 410 and the upper surface of the driving unit 300 in the motion region of the first plate 410.

In addition, the second plate 420 is coupled to the second rotation shaft 212 and the second drive shaft 312 above the first plate 410.

In this case, the second plate 420 may be coupled to the upper surface of the first plate 410 by the second rotation shaft step portion 212a and the second drive shaft step portion 312a.

In addition, it is preferable that an upper surface of the second rotation shaft step portion 212a and an upper surface of the second drive shaft step portion 312a have the same height.

In addition, it is preferable that the second rotation shaft step 212a and the second drive shaft step 312a are formed higher than the first rotation shaft step 211a and the first drive shaft step 311a, respectively.

More specifically, the upper surface of each of the stepped portion 212a of the second rotation shaft and the stepped portion 312a of the second drive shaft is a first than the upper surface of the stepped portion 211a of the first rotation shaft and the upper surface of the stepped portion 311a of the first drive shaft. It may be formed to have a height difference greater than or equal to the thickness of the plate 410.

Accordingly, when the second plate 420 continuously rotates within a certain angle, it is possible to minimize the occurrence of triboelectricity with the upper surface of the first plate 410.

In addition, it is possible to prevent abrasion occurring on the lower surface of the second plate 420 and the upper surface of the first plate 410 in the motion region of the second plate 420.

Meanwhile, since it is desirable to minimize the distance between the first and second plates 410 and 420 so that light incident to the lens barrel 110 does not leak out, the first and second drive shaft steps 311a and 312a have a semicircular shape. It is preferable that it is formed to protrude from the far side based on the center of the driving part hole 320.

Accordingly, the distance between the first plate 410 and the second plate 420 decreases toward the center of the driving part hole 320 by the load of the first and second plates 410 and 420 itself, It is possible to prevent light from leaking out at intervals of (410, 420).

Meanwhile, the cover 500 is coupled to the base 200 above the second plate 420.

In addition, the inner bottom surface of the cover 500 may be supported by contacting the upper surfaces of the first rotation shaft 211 and the second rotation shaft 212, respectively.

Accordingly, it is preferable that the top surfaces of the first and second rotation shafts 211 and 212 are formed higher than the top surfaces of the first and second driving shafts 311 and 312.

Meanwhile, the cover 500 includes a cover rotation shaft hole 530 and a cover drive shaft hole 540 at positions corresponding to the first and second rotation shafts 211 and 212 and the first and second drive shafts 311 and 312, respectively. It may contain more.

More specifically, the cover rotation shaft hole 530 is formed to have a circular shape equal to or greater than the diameter of the first and second rotation shafts 211 and 212.

In addition, the cover drive shaft hole 540 is formed at a point corresponding to the upper side of the first and second drive shafts 311 and 312, respectively, and is preferably formed in an arc shape according to the rotational motion range of the driving unit 300.

Accordingly, the first and second rotational shafts 211 and 212 and the first and second drive shafts 311 and 312 can be extended to the same height as the upper surface of the cover 500. It is possible to further prevent the plates 410 and 420 from being separated.

10A and 10B are top views illustrating operations of a driving unit and a plate of a camera module according to an embodiment of the present invention, respectively.

More specifically, FIG. 9A is a top view showing a fully open state to maximize the amount of light incident on the lens barrel 110, and FIG. 8B is a partial view to reduce the amount of light incident on the lens barrel 110. It is a top view showing the open state.

An operation example of the camera module according to the present invention will be described below with reference to FIG. 10.

When current is supplied to the coil 260, the driving unit 300 rotates by the attractive force and repulsive force generated between the coil 260 and the magnet 340.

That is, the coil 260 is fixedly coupled to the base 200, and the magnet 340 is fixedly coupled to the driving unit 300 and rotates together with the driving unit 300 rotatably coupled to the base 200. Perform.

In this case, the rotational motion of the driving unit 300 is limited by the driving unit guide groove 230 and the driving unit guide protrusion 330 so as not to exceed a certain angle as shown in FIG. 9.

In addition, the rotational motion of the driving unit 300 may be limited by the rolling member 250 and the rolling member guide 350.

Meanwhile, the frictional force generated between the base 200 and the driving unit 300 is reduced by the rolling member 250, so that rotation of the driving unit 300 is performed more easily.

As described above, when the driving unit 300 performs a rotational motion within a certain range, the first and second plates 410 and 420 perform circular motion around the first and second rotational shafts 211 and 212, respectively. do.

More specifically, when the driving unit 300 rotates in a counterclockwise direction, the first and second plates 410 and 420 rotate clockwise around the first and second rotation axes 211 and 212, respectively.

In addition, when the driving unit 300 rotates in a clockwise direction, the first and second plates 410 and 420 rotate counterclockwise around the first and second rotation shafts 211 and 212, respectively.

In addition, the first and second plate holes 411 and 421 may be formed in a shape in which a circle having a relatively large area and a hexagonal shape having a relatively small area partially overlap each other.

For example, as shown in FIG. 10A, in a low-illumination environment, a circular hole having a relatively large area of the first plate hole 411 and the second plate hole 421 overlaps upward and downward, so that a relatively large A circular incidence hole of the area is formed.

In addition, as shown in b of FIG. 10, in a high illuminance environment, a hexagonal hole having a relatively small area of the first plate hole 411 and the second plate hole 421 overlaps upward and downward to form a relatively small hexagonal shape. An incident hole is formed.

In addition, since the area of the incident hole generated by the first plate hole 411 and the second plate hole 421 is adjusted as described above, the performance of the camera module is improved by adjusting the driving unit 300 according to the illumination environment. I can make it.
